distinguishes between docker images with the same lastest etcd version but
changes (bug fixes and backward compatible improvements) to the migration
utility bundled with the image.

In addition to the latest etcd version, each `registry.k8s.io/etcd` image contains
etcd and etcdctl binaries for older versions of etcd. These are used by the
migration operator utility when performing downgrades and multi-step upgrades,
but can also be used as the etcd target version.
